Question

How much mometom with an object of mass 10kg transfer to the floor ,of it falls from a hight of 0.8m ?(g=10m/s2)

Answer 1

The final momentum of ball just before hitting the floor will be transferred to the floor.

So final velocity of ball v = √(2gh) = √(2*10*0.8) = 4 m/s

Final momentum of ball = mv = 10 *4 = 40 Ns
